Our Candy N1B frost free fridge/freezer has started to flash the green light, accompanied by what sounds like the compressor trying to start up, but cutting out again, so it becomes a constant clicking.
The heat exchanger panel in the back of the freezer compartment was totally frozen up, so I'm assuming that the auto defrost heater is not switching in.
What is the cause of this and how can I fix it?

Mine had the same problem and needed a new PCB. This fixed the problem
